[0034] See also Figure 1 , the following combination Figure 1 A spraying system for an oil mixture provided in an embodiment of the present application is described in detail.

[0035] The present application embodiment provides a spraying system for an oil mixture, such as Figure 1 As shown, the oil mixture spraying system includes an oil mixing device 1, an oil conveying device 2, an oil circulation device 3 and an oil spraying device.

[0036] Among them, the output end of the oil mixing device 1 is connected to the input end of the oil conveying device 2, the output end of the oil conveying device 2 is connected to the input end of the oil circulation device 3, the first output end of the oil circulation device 3 is connected to the oil spraying device, and the second output end of the oil circulation device 3 is connected to the oil mixing device 1; the oil conveying device 2 is used to convey the oil mixture in the oil mixing device 1 to the oil spraying device through the oil circulation device 3 when the oil circulation device 3 is in the first conduction state, and the oil conveying device 2 is also used to reflux the oil mixture to the oil mixing device 1 through the oil circulation device 3 when the oil circulation device 3 is in the second conduction state.

[0037] In the embodiment of the present application, the oil mixing device 1 is used to mix and hold the oil mixture, wherein the oil mixture is a mixture of palm oil and materials. Specifically, the oil mixture in the present application is a mixture of powdered seaweed, palm oil and seasoning powder. Therefore, the oil mixture is an oil mixture in the form of a viscous liquid. The oil conveying device 2 is a device capable of conveying the oil mixture in the form of a viscous liquid. The oil circulation device 3 is a device for controlling the flow direction of the oil mixture. When the oil circulation device 3 is in the first conduction state, the oil conveying device 2, the oil circulation device 3 and the oil spraying device are in a connected state. When the oil circulation device 3 is in the second conduction state, the oil conveying device 2, the oil circulation device 3 and the oil mixing device 1 are in a connected state. The oil spraying device is a device for spraying the oil mixture in the form of a viscous liquid.

[0038] Furthermore, the present application provides an oil mixing device 1, an oil conveying device 2, an oil circulation device 3 and an oil spraying device, so that the oil conveying device 2 can be used to convey and reflux the oil mixture when the oil circulation device 3 is in different conduction states, so that the oil spraying device can be used to evenly spray the oil mixture, so that the mixing of the oil mixture and other semi-finished products is more even. At the same time, the reflux of the oil mixture can prevent the oil mixture in the oil mixing device 1 from sinking to the bottom, thereby improving the spraying efficiency and accuracy, and further achieving even mixing of the oil mixture and other semi-finished products.

[0039] In actual applications, the oil conveying device 2 includes a pneumatic diaphragm pump 21 that can convey an oil mixture in the form of a viscous liquid. The pneumatic diaphragm pump 21 is used to convey the oil mixture in the form of a viscous liquid without causing blockage. At the same time, the pulse vibration of the pneumatic diaphragm pump 21 is low, thereby enabling stable transmission of the oil mixture.

[0040] Among them, the reason why the pneumatic diaphragm pump 21 is used to convey the oil mixture in the form of a viscous liquid is because the pneumatic diaphragm pump 21 is a device driven by an air source, and it is suitable for conveying the oil mixture in the form of a viscous liquid in a humid environment. The air source is a device that can generate, process and store compressed air. It is the power source of the pneumatic equipment and can convert the mechanical energy output by the prime mover into the pressure energy of compressed air and convey it to the pneumatic equipment to drive the pneumatic equipment to operate. It should be noted that the oil conveying device 2 cannot be a gear pump, peristaltic pump, screw pump, rotor pump, etc. driven by a motor. This is mainly because the above-mentioned various pumps driven by a motor cannot drive the conveying of the oil mixture in the form of a viscous liquid.

[0041] In a specific embodiment, the spraying system of the oil mixture also includes a control device 5, which includes an air source, wherein the air source and the pneumatic diaphragm pump 21 are connected through an air pipeline, and an electromagnetic valve is provided on the air pipeline for controlling the air flow between the air source and the pneumatic diaphragm pump 21.

[0042] In a specific embodiment, Figure 1 As shown, metal wire soft conveying pipes 6 are provided between the oil mixing device 1 and the oil conveying device 2, between the oil conveying device 2 and the oil circulation device 3, between the oil circulation device 3 and the oil spraying device, and between the oil circulation device 3 and the oil mixing device 1.

[0043] In the embodiment of the present application, the metal wire soft conveying pipe 6 can be a transparent hose made of polyurethane material and steel wire or a transparent hose made of polyurethane material and iron wire. Preferably, the metal wire soft conveying pipe 6 is a transparent hose made of polyurethane material and steel wire. Specifically, the metal wire soft conveying pipe 6 has a three-layer structure, including an inner layer, a reinforcement layer and an outer layer. The inner layer is made of transparent polyurethane material to provide a smooth and flat surface, which helps to reduce friction when conveying a viscous liquid oil mixture and allows observation of the flow of the oil mixture in the pipe. The reinforcement layer is usually composed of spiral steel wire to provide support and pressure resistance for the hose, so that it can withstand a certain internal pressure and external extrusion. In some embodiments, the steel wire is galvanized steel wire or stainless steel wire, etc. The outer layer is made of polyurethane material, which has the characteristics of wear resistance, aging resistance, UV resistance, etc., and is used to protect the internal structure from the influence of external environment such as temperature, chemicals and physical pressure.

[0044] Furthermore, the present application sets a metal wire soft conveying pipe 6 between the oil mixing device 1 and the oil conveying device 2, between the oil conveying device 2 and the oil circulation device 3, between the oil circulation device 3 and the oil spraying device, and between the oil circulation device 3 and the oil mixing device 1, so that the metal wire soft conveying pipe 6 can be used to realize the transmission of the oil mixture in the form of a viscous liquid, and it is also convenient to disassemble and clean the metal wire soft conveying pipe 6. It should be noted that the liquid outlet in the oil mixing device 1 is arranged on the side wall of the oil mixing device 1 and is located at the bottom of the oil mixing device 1, so that while facilitating the outflow of the oil mixture, the oil mixture in the oil mixing device 1 can also be in a slow flow state during the entire spraying process, thereby helping to reduce the precipitation of the oil mixture in the oil mixing device 1.

[0045] In actual applications, the diameter of the metal wire flexible conveying pipe 6 is 15 mm to 30 mm. Optionally, the diameter of the metal wire flexible conveying pipe 6 is any value between 15 mm and 30 mm. Exemplarily, the diameter of the metal wire flexible conveying pipe 6 is 15 mm, 20 mm, 25 mm or 28 mm, etc. Preferably, the diameter of the metal wire flexible conveying pipe 6 is 25 mm. Then, by setting the metal wire flexible conveying pipe 6 with a diameter of 25 mm, it is convenient to transport the oil mixture in a viscous liquid. It should be noted that the diameter refers to the nominal diameter of the pipe.

[0046] In an optional embodiment, if Figure 1 As shown, the oil circulation device 3 includes a three-way pneumatic control valve 31, which is used to control the flow direction of the oil mixture. When the three-way pneumatic control valve 31 is in a first conduction state, the oil conveying device 2, the oil circulation device 3 and the oil spraying device are in a connected state. When the three-way pneumatic control valve 31 is in a second conduction state, the oil conveying device 2, the oil circulation device 3 and the oil mixing device 1 are in a connected state.

[0047] In the embodiment of the present application, the three-way pneumatic control valve 31 is a control valve driven by an air source. Specifically, the three-way pneumatic control valve 31 is connected to the air source through an air pipeline, and an electromagnetic valve is provided on the air pipeline so that the electromagnetic valve can be used to control the gas flow between the three-way pneumatic control valve 31 and the air source. When the three-way pneumatic control valve 31 is in a first conduction state, the oil conveying device 2, the oil circulation device 3 and the oil spraying device are in a communication state, and the oil spraying device can spray the oil mixture. When the pneumatic control valve 31 is in a second conduction state, the oil conveying device 2, the oil circulation device 3 and the oil mixing device 1 are in a communication state, which can avoid the oil mixture in the oil mixing device 1 from sinking to the bottom, improve the spraying efficiency and accuracy, and further make the oil mixture and other semi-finished products evenly mixed.

[0048] Among them, when the three-way pneumatic control valve 31 is in the first conduction state, the oil mixture can only flow to the oil spraying device through the three-way pneumatic control valve 31, and when the three-way pneumatic control valve 31 is in the second conduction state, the oil mixture can only flow to the oil mixing device 1 through the three-way pneumatic control valve 31.

[0049] In another specific embodiment, the three-way pneumatic control valve 31 can also be in a third conduction state. Specifically, when the three-way pneumatic control valve 31 is in the third conduction state, the oil mixture can flow to the oil spraying device through the three-way pneumatic control valve 31, and can also flow to the oil mixing device 1 through the three-way pneumatic control valve 31, wherein a first flow value of the oil mixture flowing to the oil spraying device and a second flow value of the oil mixture flowing to the oil mixing device 1 can be the same or different, that is, the first flow value and the second flow value can be controlled by adjusting the opening of the two output ports of the three-way pneumatic control valve 31, and further, the three-way pneumatic control valve 31 can be used to realize the spraying of the oil mixture while avoiding the oil mixture in the oil mixing device 1 from sinking to the bottom, thereby improving the spraying efficiency and accuracy.

[0050] In an optional embodiment, if Figure 1 As shown, the oil spraying device includes an oil spray gun 41, a flat atomizing nozzle 42 and a solenoid valve assembly 43; wherein, the input end of the oil spray gun 41 is connected to the first output end of the oil circulation device 3 through a metal wire soft conveying pipe 6, the output end of the oil spray gun 41 is connected to the input end of the flat atomizing nozzle 42 through a metal wire soft conveying pipe 6, and the atomizing end of the flat atomizing nozzle 42 is arranged toward the mixing and containing device; the solenoid valve assembly 43 is arranged on the gas conveying channel between the air compression device and the flat atomizing nozzle 42, and the solenoid valve assembly 43 is used to control the air circulation between the air compression device and the flat atomizing nozzle 42.

[0051] In the embodiment of the present application, the flat atomizing nozzle 42 is a wide duckbill fan-shaped nozzle. In practical applications, the width of the flat atomizing nozzle 42 is 40 mm to 90 mm. Optionally, the width of the flat atomizing nozzle 42 is any value between 40 mm and 90 mm. For example, the width of the flat atomizing nozzle 42 is 40 mm, 45 mm, 50 mm, 65 mm, 75 mm, 80 mm or 90 mm, etc. Preferably, the width of the flat atomizing nozzle 42 is 65 mm. Further, the width of the gap inside the flat atomizing nozzle 42 is 2 mm to 3 mm. mm, optionally, the gap width inside the flat atomizing nozzle 42 is 2 mm, 2.3 mm, 2.5 mm, 2.8 mm or 3 mm, etc., preferably, the gap width inside the flat atomizing nozzle 42 is 2.5 mm, and then, by setting a flat atomizing nozzle 42 with a width of 65 mm and a gap width of 2.5 mm to meet the spraying requirements, and then, by setting an oil spraying device including an oil spray gun 41, a flat atomizing nozzle 42 and a solenoid valve assembly 43, so as to improve the spraying effect and efficiency, the oil mixture is evenly mixed with other semi-finished products.

[0052] In a specific embodiment, the oil spray gun 41 is a spray gun driven by an air source, and the oil spray gun 41 and the air source are connected by an air pipeline, and a solenoid valve is provided on the air pipeline, and the solenoid valve is used to control the gas flow between the oil spray gun 41 and the air source. The solenoid valve assembly 43 includes multiple solenoid valves. Specifically, the solenoid valve assembly 43 includes 4 solenoid valves, wherein one solenoid valve is used to control the air flow between the air source and the pneumatic diaphragm pump 21, one solenoid valve is used to control the gas flow between the three-way pneumatic control valve 31 and the air source, one solenoid valve is used to control the gas flow between the oil spray gun 41 and the air source, and one solenoid valve is used to control the air flow between the air compression device and the flat atomizing nozzle 42. It should be noted that the number of solenoid valves in the solenoid valve assembly 43 can be increased or decreased on this basis, so that the corresponding solenoid valves can be used to control the flow of gas or liquid.

[0053] In actual applications, the driving voltage of the solenoid valve is 24V. Therefore, during the process of driving the solenoid valve, even if liquid is sprayed on the solenoid valve, causing the solenoid valve to short-circuit, it will not output high voltage to injure the user.

[0054] In a specific embodiment, the spraying system of the oil mixture also includes a mixing and containing device 8 and a semi-finished food product supporting device 9, wherein the product outlet of the semi-finished food product supporting device 9 can be moved toward the inlet of the mixing and containing device 8, and then the semi-finished food product supporting device 9 can transfer the semi-finished product that needs to be sprayed with the oil mixture to the mixing and containing device 8, thereby achieving uniform mixing of the semi-finished product and the oil mixture in the mixing and containing device 8.

[0055] In a specific embodiment, Figure 1 As shown, the oil spraying device also includes a pressure regulating valve 44 and a throttle valve 45, and the solenoid valve assembly 43 includes a first solenoid valve, which is used to control the air circulation between the air compression device and the flat atomizing nozzle 42; wherein, the pressure regulating valve 44 is arranged on the gas delivery channel between the air compression device and the first solenoid valve, and the throttle valve 45 is located on the gas delivery channel between the first solenoid valve and the flat atomizing nozzle 42, and is arranged close to one end of the flat atomizing nozzle 42.

[0056] In the embodiment of the present application, the air compression device is used to provide compressed air to the flat atomizing nozzle 42, so that the compressed air can be used to atomize the oil mixture in the flat atomizing nozzle 42, thereby realizing atomization spraying of the oil mixture, making the mixing more uniform. Furthermore, by setting a pressure regulating valve 44 on the gas delivery channel between the air compression device and the first solenoid valve, and setting a throttle valve 45 on the gas delivery channel between the first solenoid valve and the flat atomizing nozzle 42, the pressure and flow value of the flat atomizing nozzle 42 can be adjusted, thereby preventing the air pressure and air volume from being too high, so that the oil mixture cannot be mixed and atomized and sprayed with the compressed air output by the air compression device.

[0057] In an optional embodiment, if Figure 1 As shown, the spraying system of the oil-fuel mixture further includes a control device 5 and a stirring device 11, wherein the control device 5 includes a frequency conversion mechanism 51; wherein the driving end of the frequency conversion mechanism 51 is connected to the stirring device 11, and the stirring end of the stirring device 11 is located in the oil-fuel mixing device 1 and extends to the bottom of the oil-fuel mixing device 1.

[0058] In the embodiment of the present application, the frequency conversion mechanism 51 can be a frequency conversion drive, and the stirring device 11 can be a stirring paddle or a stirring rod, etc. Furthermore, the present application arranges a stirring device 11 extending to the bottom of the oil mixing device 1 in the oil mixing device 1 so that the stirring device 11 can be used to stir the oil mixture in the oil mixing device 1, thereby avoiding the oil mixture from sinking to the bottom and improving the spraying efficiency and accuracy. At the same time, a frequency conversion mechanism 51 is also arranged to control the output of the stirring device 11, and the frequency conversion mechanism 51 can be used to reduce the stirring frequency of the stirring device 11, thereby avoiding the splashing of the oil mixture and improving the spraying accuracy.

[0071] S102 : when receiving the instruction to prevent the oil mixture from settling in the oil mixing device 1 , controlling the oil circulation device 3 to be in the second conduction state, so that the oil mixture flows back into the oil mixing device 1 through the oil circulation device 3 .

[0072] Specifically, when receiving a spraying request, the control device 5 can control the three-way pneumatic control valve 31 in the oil circulation device 3 to be in the first conduction state, so that the oil conveying device 2, the oil circulation device 3 and the oil spraying device are in a connected state. At this time, the oil conveying device 2 can convey the oil mixture in the oil mixing device 1 to the oil spraying device through the oil circulation device 3, so that the oil mixture can be sprayed by the oil spraying device, thereby achieving uniform spraying of the oil mixture, so that the oil mixture and other semi-finished products are mixed more evenly.

[0073] Furthermore, when the control device 5 receives an instruction to prevent the oil mixture in the oil mixing device 1 from settling, it can control the three-way pneumatic control valve 31 to be in the second conduction state, so that the oil conveying device 2, the oil circulation device 3 and the oil mixing device 1 are in a connected state. At this time, the oil conveying device 2 can return the oil mixture to the oil mixing device 1 through the oil circulation device 3, thereby preventing the oil mixture in the oil mixing device 1 from sinking to the bottom, improving the spraying efficiency and accuracy, and further making the oil mixture and other semi-finished products evenly mixed.

[0074] It should be noted that since the spraying control method for spraying the oil mixture is implemented based on the above-mentioned spraying system of the oil mixture, it has all the beneficial effects of the spraying system of the oil mixture, so the beneficial effects of the spraying control method for spraying the oil mixture will not be elaborated here.
